Sensitivity Control 37
Sensitivity control and error panel

PP8 is very precise in its color discrimination. It can compen-
sate for subtle differences in color and detect the target markers.

If there is a problem, PP8 will display the dot pattern recognized

by the software in an effort to help you locate the offending color than might be in the back-
ground or on an article of clothing. To illustrate this we have created a potential problem for
PP8 by using an article of clothing that is close to the color of the target dots.

When PP8 cannot locate the target dots in the correct pattern, a window will open that
shows the dots, and their screen position, as recognized by PP8. In the above sample the
display shows the normal dots for the head, shoulders, hips, ankles and knees, but also
shows a cluster of dots around the skirt area.

To solve this confusion you can use the bottom sensitivity slider to decrease the sensi-
tivity to these nontarget colors. By moving the slider from .5 to .25, and performing another
AutoAnalysis, the program increases the color discrimination for the target dot and a com-
plete exam is performed, as shown on the next page.

The top slider adjusts for dot size. Typically this is used for the 1.25" dots and a close-
up picture.
